Fort Hamilton's Marvin Centeno is done for the year with a broken collarbone.Denis Gostev

If Fort Hamilton is going to repeat as city champion, the Tigers will have to do so without senior quarterback Marvin Centeno.

The talented signal-caller suffered a broken collarbone in Saturday’s 32-14 loss to Erasmus Hall, which snapped Fort Hamilton’s 38-game, regular-season winning streak, and will almost certainly not return for the playoffs, coach Danny Perez told The Post.

“He’s heartbroken,” Perez said. “This is his senior year. He was having such a great year, too. Marvin’s a great kid and it’s tough.”

In his place will be dynamic junior Travon Reid Segure, a safety/wide receiver who already has a scholarship offer from Syracuse. Fort Hamilton used fullback/middle linebacker Robert Thomas under center because Segure was still nursing a sore right shoulder. He’ll be at quarterback Saturday against winless FDR.

“Travon can do some special things at quarterback,” Perez said of Segure, who has two interceptions and 22 tackles on defense and has scored three touchdowns on offense. “Travon’s a good athlete, he can definitely throw. He’s gonna operate the offense. … The tough part is losing the leadership Marvin brought.”

In seven games, Centeno threw for 398 yards and eight touchdowns while also running for 682 yards and seven scores. In a Week 5 win over Thomas Jefferson, he rallied the Tigers from a 14-point hole, running for 226 yards and a touchdown.

“We won the game on his shoulders,” Perez said. “He was the main leader of the team.”

Fort Hamilton still feels it’s a title contender. The offense will remain run-heavy, behind Segure and running backs Tyrone Raymond and Stefon Hayles and Centeno didn’t play defense, so the unit remains at full strength.

“We’ll battle through and keep moving forward,” Perez said.

Beach Channel forfeit due to medical ineligibility: Victor Nazario wants to clear the air. The Beach Channel coach has heard a lot of talk the last few weeks about his team forfeiting a Week 4 game to James Madison due to ineligible player.

“Everyone out there now is assuming I’m playing ineligible players,” Nazario said. “I’ve never done and never have any intention of doing that. We have people jumping to conclusions here, that we were forfeiting the whole season.”

The player – Nazario would not give his name – is in fine academic standing. The issue was a medical one. The player told the Beach Channel coaching staff he was cleared after a “minor procedure” on his knee and he was allowed to play against Madison. Coincidentally, the player has a relative on Madison, who told the Knights coaches that he had not been cleared and was ineligible, according to Madison coach Tom Mobilia.

Nazario said the ineligible player was only in the game on 10 or 12 downs and he did not make an impact. Not only is he upset that his program reputation has been spoiled, Beach Channel, once thought to be the heavy favorite to win the Bowl division, lost the next two games and is now no longer a lock to even make the playoffs.

“It was definitely a distraction, because everyone knew,” Nazario said. “We’re definitely the best team in this division, I don’t care. It would be a shame for a team like this to miss the playoffs.”

The Dolphins got back on the winning track this week, pounding Long Island City, 40-14. But now Saturday they have undefeated Bayside coming up. Beach Channel might have to win out to earn a postseason berth. The top six teams in the league make the layoffs.

“Once we get in, it’s a wrap,” Nazario said. “We’re [upset]. … I guess they gotta get desperate out there [at Madison] and pull wins out anywhere they can.”

Lafayette on the rise: There are freshmen on Lafayette’s roster who remember rock bottom. The Patriots were 0-9 in 2008, a second straight winless season.

Things looked bleak back then. The school was undergoing a restructuring. But that same group that came in three years ago is now helping lead Lafayette to its best season in more than a decade. The Patriots are 5-2 in their first year up in the Bowl division, led by seniors Gregory Lenord, John Rodriguez and Ronnie Smith. On Saturday, they beat Automotive, 42-0, just two years after that same team spanked them, 72-0. That loss stuck with the young players who are now juniors and seniors.

“It felt good for the kids,” coach Tom Vitola said. “A lot of those kids played in that game when they were getting smacked around.

Vitola is in his first year as head man, taking over for Michael Rubino, who stepped down for family reasons but is still an assistant. Vitola is in his fourth year at Lafayette, but made his bones coaching and playing at Sheepshead Bay under Fred Snyder.

A once-proud program, Lafayette has not made the playoffs at any level since Chris App left for New Dorp after the 1995 season. Right now, the Patriots are in fourth place in the Bowl, where six teams go to the postseason.

That’s only one place the Bensonhurst squad wants to be, though. Vitola wants to be in the City Championship division as soon as possible, perhaps even next year. In Big Apple Games and HSPD, the Lafayette players work out with kids from Fort Hamilton, Lincoln, Sheepshead Bay and the other Brooklyn powerhouses.

“They see what the work ethic and what they need to be to be on the 5 level,” Vitola said. “Their goal is to be there and our goal as a staff is to be there.”

Henry putting up big numbers for Petrides: When Joe Henry arrived at Petrides, he had zero football experience. No Pop Warner games, not even two-hand touch. He was a soccer player and just used his raw physical ability as a running back.

“If the hole was there, great; if it wasn’t he would try to make the hole,” Petrides coach David Olah recalled. “There was no variation to it.”

Henry has matured over the last few years and has emerged as the Cup division’s top running back with 1,260 yards and 11 touchdowns. He enjoyed a season’s worth of production in one game Saturday, running for 333 yards on 23 carries and six touchdowns in the Panthers’ 46-24 rout of Adlai Stevenson, their second straight win.

“He’s much more patient,” Olah said of the 5-foot-8, 180-pound Henry, who is also the team’s starting middle linebacker and has drawn interest from College Football Subdivision programs Albany and Wagner. “He’s allowing things to develop in from in him. It’s allowed him to have bigger runs this year.

“He’s learning more and more about football and he just really understands the game really well this year.”

Notes: Erasmus Hall sophomore prodigy Curtis Samuel is still out with an abdominal strain. Dutchmen coach Danny Landberg said Monday he’s not sure when Samuel will be back, but probably not Saturday against Grand Street Campus. … The two City Championship division quarterbacks with the most touchdown passes didn’t even start a year ago. Campus Magnet’s Kahlik Greenwood and Lincoln’s Jessel Jones have tossed 11 and 10 scoring strikes, respectively. … Lincoln is the only remaining undefeated team in the City Championship division.
